Twitter on shadowbanning. My favourite part is this (emphasis added):
We do not shadow ban. You are always able to see the tweets from accounts you follow (although you may have to do more work to find them, like go directly to their profile). And we certainly don’t shadow ban based on political viewpoints or ideology.
We do rank tweets and search results. We do this because Twitter is most useful when it’s immediately relevant. These ranking models take many signals into consideration to best organize tweets for timely relevance.
In other words, “We don’t shadowban… except when we totally do (because we’re too chickenshit to actually moderate our platform properly).”
Polite reminder in these turbulent times that Mastodon is totally a thing.
